My two year old suunto m2 isn't giving me me a correct hr reading. I have changed both batteries and washed the strap. Help! Is it time for a new watch?

    I had the M2, and then upgraded to the M5 simply for the back light.

    How are you sure it's not giving you a correct HR reading?

    Try resetting it completely.

    Do your exercise, take your HR manually and see if it matches the HRM. If not, the HRM isn't working.
